DESCRIPTION The SPX385-1.2 is a micro 2-terminal bandgap voltage reference with a very wide operating current ranging from 10µA to 20mA to provide a regulated voltage. The high stability of this device is primarily the result of a low temperature coefficient thin film resistor process, laser trimming the output voltage at the wafer level. The SPX385-1.2 is available in a TO-92 and SOIC-8 and SOT-89 packages and operates over a temperature range of -40°C to 85°C. A 2.5 and 5.0 volt device is also available - SPX385- 2.5, SPX385- 5.0 .
